Anarchism

It also comes with a tiny minority of people, mostly on the auth "left" side, who dislike liberals not only because of their lack of radicalism, but also for their support of some progressive views (in my experience especially on gender, and also a bit on racism). Like, people who are progressive in regard to proletarian struggle, but conservative for other matters. It is a really tiny fraction, but they can be vocal at times, and most importantly their ideas can spread to other people who are not real conservatives, but who don't care or care less about other oppressions than class struggle. And i think using liberal as an insult can push people in that direction.
